Is ByNoGame Auto Trader safe?

Low risk

ByNoGame Auto Trader imports Socket.IO code from cdn.socket.io into its privileged background service worker.

The extension's background service worker loads a remote Socket.IO module from cdn.socket.io before initializing its socket service. That downloaded code runs in the extension context with access to declared permissions, including cookies, credentials, stored extension data, and tab information for permitted sites.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

What this publisher told the store about itself, and the other listings that told it the same thing.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data

Destinations our analysis observed ByNoGame Auto Trader contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • cdn.socket.io

    ByNoGame Auto Trader sends data to cdn.socket.io. No other extension we have analysed sends data here.
